NSHBG-12
NSHBG-12 12kV environmentally friendly gas insulated ring main unit is a flagship equipment for high-end precision manufacturing and intelligent microgrids. It adopts a new low GWP environmentally friendly mixed gas (GWP value ≤ 5), integrates AI intelligent diagnostic unit, high-precision transformer, non-destructive expansion module, and integrates drawer type modular design and microgrid linkage technology. It meets the dual high standards of GB/T 11022 and IEC 62271. The equipment focuses on scenarios such as semiconductors, biopharmaceuticals, and smart park microgrids, with ultra-low partial discharge, precise power supply, and intelligent linkage as the core, to achieve green and intelligent power supply upgrades in high-end scenarios.
1. Outstanding precision power supply capability, partial discharge level ≤ 5pC, voltage deviation controlled within ± 0.5%, can effectively avoid electromagnetic interference and voltage fluctuations, suitable for high-end loads such as precision instruments and quantum equipment.
2. Top environmental performance, the new mixed gas insulation has better arc extinguishing performance than traditional environmental protection media, and can be 100% recycled, purified and reused. The carbon emissions throughout the entire life cycle are reduced by 98% compared to SF ₆ equipment.
3. Intelligent linkage is leading, equipped with edge computing AI module, which can analyze multi-dimensional operation data in real time, realize fault prediction, dynamic load deployment, and seamlessly link energy storage and microgrid systems; The fourth is the convenience of non-destructive expansion, using patented technology for live expansion.

Yes, the device adopts a low electromagnetic radiation structure design, and the electromagnetic interference (EMI) meets Class B standards. The local water level is extremely low, which will not interfere with quantum instruments and precision sensors.
Through multidimensional data modeling and algorithm analysis, potential faults (such as seal aging and component wear) can be predicted 72 hours in advance, and maintenance suggestions can be pushed to reduce the risk of sudden shutdown.
Easy to operate, using dedicated expansion interfaces and tools. Professional operation and maintenance personnel can complete single circuit expansion in 1-2 hours without affecting the original circuit power supply or requiring complex approval processes.
